Web Forms :: Regular Expression To Replace All Special Characters?

Jan 18, 2010

I am trying to write a regular expression to replace all special chracters within a string so that I am left with just alphanumeric characters and spaces or full stops.

I am using this expression at the moment

[Code]....

But then I test this with the string "This is a test!", it returns "Thisis a test", which would be fine, except for the space it removes between "This" and "is", can anyone else me where I am going wrong or supply a better expression?

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.

How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*

Web Forms :: Regular Expression Validator For Both English And Chinese

May 7, 2015

Earlier my text box was running on this Validation Expression="^[a-zA-Z'.s-]{1,80}$", to allow only alphabets,  ' . s . Now my text box should be capable of taking Chinese characters as well, so I was learnt online to use this p{L} for unicode instead of  a-zA-Z, and set EnableClientScript="false".

asp:RegularExpressionValidator ID="regexpName" runat="server" CssClass="failureNotification" ErrorMessage="No Special Characters allowed"
ControlToValidate="txtName" ValidationExpression="^[p{L}'.s-]{1,80}$" Display="Dynamic" meta:resourcekey="regexpNameResource1" EnableClientScript="false"

I have done both, but it doesn't work. My input values were like

1. John123 2. 汉语%^&

Both of these were accepted without any errors. But I expect only alphabets in english and chinese and ' . s - to be accepted as Name input.
